SPECIFICATION forming part of Letters Patent No. 578,245, dated March 2, 1897.

Application led September 12, 1896. Serial No. 605,633. (No model.)

To all whom t may concern:

Be it known that I, ADONIRAM J. KINNAIRD, of Standish, Carroll county, Missouri, have invented certain new and useful Improvements in Gates, of which the following is a full, clear, and exact description', reference being had to the accompanying drawings, forming a part thereof.

My invention relates to gates, and more particularly to that class which may be both opened and closed by a person upon a vehicle.

The object of my invention is to produce a gate of this character which is positive and reliable, easy of operation, and sim ple, strong, durable, and inexpensive of construction.

With this object in view the invention consists in certain novel and peculiar features of construction and combinations of parts, as will be hereinafter described and claimed.

In order that the invention may be fully understood, I will proceed to describe it With reference to the said accompanying drawings, in Which- Figure 1 represents .a plan view of a gate embodying my invention. Fig. 2 represents, on an enlarged scale, a section taken on the line II II of Fig. 1. Fig. 3 represents a longitudinal section of a bar which carries the gate-operating mechanism. Fig. 4 represents a perspective View of a gate provided with a slight1y-modiiied form of operating mechanism. Fig. 5 is a top plan view of the same.

Similar reference-numerals designate corresponding parts in all of the gures.

1 designates the hinge-post of a gate 2, and 3 the latch-post, provided with the customary hook-catch 4.

The latch is a compound latch, comprising a front piece 5, pivotally mounted to operate in a vertical plane, as at 6, upon the gate and adapted to engage the hook4 at its front end, and a piece 7, which is pivotally mounted, as at 8, upon the gate and is stepped upon or into the rear end of the piece 5, so that when the front end of said piece 7 is depressed it pivotally operates the piece 5 and disengages it from the hook 4.

10 designates a diagonal brace which is secured to the longitudinal rails 8 and bears at its lower end against the front bar thereof and at its rear end is bolted, as at 11, to the upwardly-extending end of the rear bar of the gate. This diagonal brace obviously prevents any possible sagging of the gate at its front end while in operation or when standing open or closed. Secured rigidly in the plane of and to the top rail of the gate and said diagonal brace is'the supporting-bracket 12 for the lever-supporting bar 13, which projects rearwardly from the gate and at an angle of about forty-ive degrees from the longitudinal plane of the same, as shown most clearly in Fig. 1. Adjacent to the hinge of the gate said bar 13 is recessed and carries the oblong bracket 14, extending ltransversely of said bar, and j ournaled in the bracket edge to edge are a pair of antifriction-rollers 15, below and between which the bar 13 is provided with a vertical opening 16.

17 designates a rocking lever which is mounted to operate in a horizontal plane upon the bar 13 and at its front end normally overhangs the space between the antifriction-rollers 15, and attached permanently to said end, as shown at 18, is the cord or chain 19, extending vertically downward through the opening 16 and attached at its lower end to the loop or eyebolt 20, secured to the rear end of the compound latch. The movement of said lever is limited by means ofthe U-shaped bracket 21, secured to the rear end of the bar 13, for a purpose which will hereinafter appear, and the rear end of said lever 17 is connected, as at 22, to the opposite ends of an operating-cable 23, which cable connects and is coiled once or more around a pair of drums 24 and 25, provided with crank-handles 26, by which they are operated. The brackets in which said drums are journaled are mounted upon the horizontal bar or bars 27, which extends or extend at right angles to the gate just back of the hinge-post and preferably vertically below the pivotal point of said lever. Said bar or bars 27 are supported by the hinge-post and one or more posts 28, and the post 28, at the side toward which the gate opens, is arranged the same distance from the hinge-post as the post 3, and is also provided with a hook-catch 29 to engage the latch and hold the gate open at times, as shown in dotted lines, Fig. 1.

It will be apparent by reference to Fig. 1 that when the gate is closed the ends of the ICO cable 23 extend divergently forward to said drums, in order that apurchase or leverage may be had at the initial or opening movement of the gate. In practice when the gate is in such position a person may drive up straight or from either side, as the bar 27 is sufficiently high to permit the front wheel of the vehicle to pass beneath it, which obviously permits the driver to get very close to the crank-handles of the drums. I-Ie then starts to rotate said drum, and this movement obviously first swings the lever in the direction indicated by the arrow, Fig. 1, until it strikes one end of the U -shaped bracket and simultaneously operates and disengagesthe compound latch from the hook el.. The continued rotatable movement of the drum then causes, by reason of the engagement of the lever 17 with said bracket 21, the gate to swing open, and it will be apparent that by reason of arranging the bar 13 at the angle shown with relation to the gate the leverage upon the gate, through the medium of the lever 17, is continued until the gate assumes its open position at right angles to the position shown in full lines, and the bar 13 extends also ati-ight angles to its normal position.

lith the majority of gates of this class when the gate is about half-open and when the leverage is needed most it diminishes, as a rule, but with my construction it will be apparent that when the gate is half-open the leverage is greater than at the beginning of such movement and that it increases as the gate is opened, as will be apparent from the new position (shown in dotted lines) of said lever 17 in Fig. 1. After passing through the gate the operator grasps the other crankliandle. 26 and rotates its drum in the proper direction. This of course rst swings the lever to the position shown in dotted lines, Fig. 1, and raises the latch from engagement with the hook 29, and the rotatable movement of the drum continuing the gate is swung back to its closed position, the latch, of course, automatically engaging the hook 14C in the customary manner.

The arrangement thus far described is applied approximately in the plane of a gate of ordinary height.

I will now proceed to describe the slightlymodified form. In this form the substitute for the bar 13 is double the length of said bar, and duplicate levers and operating cords or cables are employed, and because of the increased length of said substitute bar it must be arranged at a greater height than any vehicle which may pass through the gate, for a purpose which will be hereinafter made apparent. Referring now to said modified construction, as illustrated in Figs. It and 5, it will be noticed, in the first instance, that the hinge-post must also be of increased length, and that to give perfect rigidity to the gate one of its end bars is extended vertically beyond the upper end of said hingepost, or such a bar may be secured to said end bar, and the diagonal brace of thegate, also ofigreater length, is bolted to the upper end of said extended bar. The horizontal bar 13 is secured rigidly to said extended bar above the top of the hinge-post and extends at the same angle, preferably, as the bar 13, but in this case it projects forwardly beyond the hinge-post and consequently overhangs the roadway, and for this reason must be above the top of any vehicle which may pass through the gate. Said bar to the rear of said hingepost carries the lever 17, which operates in connection with antifriction-rollers 15, journaled in the bracket 14, and said lever is connected, as before, to the rear end of the latch. At the opposite side of the latchv a similar lever 171 is mounted, and said lever operates-in conjunction with a cord 19n and a pair of similar antifriction-rollers 15, journaled in a bracket'let", like the bracket 14;. The lateral movement of the lever 17 is limited by the bracket 21, and the lateral movement of the bracket 17 islimit-ed by the bracket 21u. At the outer ends-` of the bars 27, as shown in Fig. 4, are mounted brackets which carry the pulleys 30, which preferably are of the double-grooved type, but thisis not important, and extending` over said pnlleys are the operating cords or cables 31 and 32. The inner ends of said cords are attached, as at 22, to the rear end of the lever 17 and carry at their opposite ends the depending handles-33 and'34, respectively; EX- tending also over said pulleys are a pair of operating.- cords-35 and 36, and these are attached at their inner ends, asiat 22, to the lever 17 and carry pendently at their opposite ends the operating-handles 37 and 3S, respectively.

In practice the gate isa-opened by pulling down upon the handle 34C or 37. In either case the lever 17 or 17a is operated as-bcfore described and causes first the disengagement of the latch from the hook through the medium of the cord 19 or 19 and next swings the gate toits open position. This of course, by changing the position of the bar 13, lifts the handles 33 and 38, and by pulling downward upon either of them the reverse operation takes place and the gate closes.

It will be apparent, by-rcason of the edgeto-edge position of the antifriction -rollers employed, that the latch-lifting cords 19 19a always engage one or the other, and consequently friction and wear are reduced to the minimum.

Thus-it will be seen that I have produced a gate which embodies `all the features-enumerated in the statement of invention as-desirable, and it will be apparent that various changes maybe embodied in the construction of gate which do not involve a departure from the spirit and scope of the invention.

Having thus described the invention, what I claim as new, and desire-to secure by Letters Patent, is-
